 ### Improvements in Efficiency
 
 - Improved preamble detection implementation in the decoding of navigation messages (acceleration by x1.6 on average).
-- Applied clang-tidy checks and fixes related to performance.
+- Applied clang-tidy checks and fixes related to performance: performance-faster-string-find, performance-inefficient-algorithm, performance-move-const-arg, performance-type-promotion-in-math-fn, performance-unnecessary-copy-initialization, performance-unnecessary-value-param, readability-string-compare.
 
 
 ### Improvements in Interoperability:
 
 - Added the BeiDou B1I receiver chain.
 - Fix bug in GLONASS dual frequency receiver.
+- Added a custom UDP/IP output for PVT data streaming.
+- Improved Monitor block with UDP/IP output for internal receiver's data streaming.
 
 
 ### Improvements in Maintainability:
 
 - Usage of clang-tidy integrated into CMake scripts. New option -DENABLE_CLANG_TIDY=ON executes clang-tidy along with compilation. Requires clang compiler.
-- Applied clang-tidy checks and fixes related to readability.
+- Applied clang-tidy checks and fixes related to readability: readability-container-size-empty, readability-identifier-naming, readability-inconsistent-declaration-parameter-name, readability-named-parameter, readability-non-const-parameter, readability-string-compare.
+- Improved includes selection following suggestions by include-what-you-use (see https://include-what-you-use.org/), allowing faster compiles, fewer recompiles and making refactoring easier.

 ### Improvements in Reliability
 
-- Applied clang-tidy checks and fixes related to High Integrity C++.
+- Applied clang-tidy checks and fixes related to High Integrity C++: performance-move-const-arg, modernize-use-auto, modernize-use-equals-default, modernize-use-equals-delete, modernize-use-noexcept, modernize-use-nullptr, cert-dcl21-cpp, misc-new-delete-overloads, cert-dcl58-cpp, cert-err52-cpp, cert-err60-cpp.
 
 
 ### Improvements in Usability
 
 - The receiver now admits FPGA off-loading, allowing for real time operation at high sampling rates and higher number of signals and channels.
 - Fixed program termination (avoiding hangs and segfaults in some platforms/configurations).
+- CMake now generates a summary of enabled/disabled features. This info is also stored in a file called features.log in the building directory.
 - Improved information provided to the user in case of failure.
